GIS Data :: Web Maps


Much of the CGS website is under heavy re-construction and will be for some time. The Publications area is working normally, but there is a lot of content from our original site that was in desperate need of updating. Please bear with us as we gather new information and rewrite hundreds of pages of material, gather and properly caption high-resolution images and otherwise bring you some very cool new and archival material never before seen! Stay in touch by subscribing to the >RockTalk< blog where we will announce new items periodically.


As an agency often involved with spatial information, the CGS is moving more and more to dynamic GIS data presentation for ease-of-use and for the many options that GIS tools allow. Almost all of our current projects and publications have substantial GIS components. We are in the process of implementing GeMS standards for our GIS metadata which will increase the utility of our entire GIS repository. We will be adding to this data Portal on a consistent basis as we produce new publications, and in many cases, update older data.
